I guess it is safer to just assume the former is true unless I can find it explicitedly stated otherwise.
I think it's just the reservation, but I don't know for certain. You are, of course, limited by the 30/60/90 day advance booking windows. Note as well that if you cancel a points reservation, the points are returned into your account with their original expiration dates.
